Today's statement says the discovery was made in a western desert area known as Beir al-Shagala near the Dakhla oasis, southwest of Cairo.
The archaeological mission uncovered a range of artefacts, including the remains of a funerary mask, a set of pottery vessels, a clay incenses burner, a small sandstone sphinx and two ostraca, or ink-in-clay pottery shards.
One ostracon bears hieroglyphic texts while the other is scripted in hieratic, a cursive writing system used during pharaonic times.
The ministry says that the tombs, including a pyramid- shaped one and another with a domed ceiling, were built in mud-brick and contain several burial chambers.
